The city of vain death is very large, and it is not the kind of small city where you can see the opposite gate at a glance, even the capitals of those countries in the Yang world cannot be compared. After all, the purpose of this vain city is to provide a place for the souls of those who have died in vain all over the world to reside, and this world is not just a Shenhua realm.

Legend has it that the city of vain death is in the hands of the king of Bian Cheng, one of the ten palace kings, of course, no one knows what actually happened. In particular, since the heaven and earth collapsed, there are no more true immortals in the world, and no one can enter the underworld to find out. Regarding the true situation of the underworld, naturally no one knows anymore, and Ye Zan and the others only know now that this underworld has already collapsed with heaven and earth.

Speaking of returning to this vain city, it is not much different from those big cities in Yangshi, in addition to a large number of "ordinary houses", there are also many commercial buildings. Although most of the buildings in the city have now become pieces of ruins, people can still vaguely imagine the once prosperous scene in the city.

Don't think that when a person dies and becomes a ghost, he has no desires and no desires, and immortals can't do it without desires, let alone ghosts that have gathered people's will. The ghosts in the city of death are all immature and unfinished, and they can neither be reincarnated immediately, nor can they return to yang, so they can only spend their days in this city. Even if it's only a few months, if you don't have anything to do, I'm afraid you'll be driven crazy by boredom.

If there are relatives in the Yang world, they will burn some incense candles and paper ties, which will become their source of life in the city of vain. There are also some ghosts who have no relatives in the yang world, and they have no source of livelihood so they can only find ways to do it themselves, such as providing some services or fun to rich ghosts. In short, living in this vain city is actually no different from living in the Yang world, it is a small society with class differences.

Ye Zan's side is prepared, it may not be very thorough, after all, no one is truly omniscient. However, as long as he could think of it, he basically made preparations for it, and even left a small steel fortress in the open space outside the city gate. In the steel fortress, in addition to being guarded by four Genshin mechanical warriors, a large number of weapons and ammunition were also left behind.

"Enter the city!" Ye Zan waved his hand, and finally led everyone into the city of vain.

Of course, Ye Zan had already scanned the scene in the city of vain death, and a large number of marauders and insects were scouting around. Other people other than Ye Zan also had an understanding of the appearance of the city in advance through the field command vehicle and the images transmitted back by the probe. Therefore, after officially stepping into the city gate, everyone did not have much emotion and amazement at the ruined walls.

What really cared about Ye Zan and the others was the several giant crypts located in this vain dead city and scattered in several areas. The huge crypts, each the size of a football field, were pitch black and bottomless, and I didn't know where they led. There were a few crypts around the area where there were fresh traces of the fierce battle, but there were no corpses or blood, only spell bombardment or some sword marks.

Ye Zan and the others soon came to the nearest crypt, which also left a lot of traces of battle, some of which looked like they were left by huge claws.

"The three teams in front of you can't all go down here. After inspecting the surrounding traces with his own eyes, Wenhua Zhenjun looked at the bottomless crypt and couldn't help but say with some worry.

Did the three teams descend into the crypt, or did they leave the City of the Dead?

Perhaps because of the environmental problems here, Ye Zan's original tracking methods are not very easy to use here. Whether it's heat or smell, it seems to be difficult to survive here, perhaps because of the so-called excessive yin qi. This "yin qi" is not a cold breath, although it has the attribute of making people feel cold, but it also has the nature of repelling and disturbing other "energy".

Therefore, even Ye Zan could not be sure how the three teams in front of him were going.

After passing through the city of vain death, and a little further on, there is the legendary capital city, which is also the center of this netherworld. According to common sense, that Tianyu Dao Ancestor is likely to be hiding there, and maybe he has mastered some key to the underworld.

However, it is not entirely certain that the three teams will not be able to enter the crypt. After all, the appearance of these crypts is very strange, and it may not lead to the hiding place of the Tianyu Dao Ancestor. In other words, that Tianyu Dao Ancestor was not a fool, maybe even if someone thought he was hiding in the capital city, so he chose to hide somewhere else.

"Brother Xian, what do you think?" asked Qinghong Zhenjun.

"Don't worry, I'll try to probe it first. As he spoke, Ye Zan released the probe and began to probe into the depths of the crypt.

However, at this moment, everyone suddenly felt a violent vibration from the ground under their feet, as if something was about to emerge from the ground. Ye Zan and the others reacted quickly, and after all, their mana had been restored, so they immediately scattered in all directions and left the place. At the same time, they didn't run around, but faintly surrounded the ground, no matter what came out of it, they could immediately start a siege.

And as Ye Zan and the others scattered in all directions, the ground where they were originally standing quickly arched a mound. Then, the top of the mound was broken, the earth and rocks collapsed in all directions, and a large beetle with a hideous image leaped out of the ground.

This large beetle, the size of which is similar to Ye Zan's field command vehicle, looks very much like an oversized one-horned fairy. It's just that its front half of its body is erect like a human, and under the huge single horn, there is also a face similar to a human, but it looks ugly and hideous.

"What kind of monster is this!" Qinghong Zhenjun and the others had never seen such a demon beast or demon clan, so naturally they couldn't guess the origin of this big beetle.

"It's ...... Crypt Lord?" Ye Zan frowned, looked at the big beetle in front of him, and said a name in surprise.

Of course, Ye Zan was not sure that this great beetle was the so-called Crypt Lord. The reason why he said this was only because he found information on a similar creature in his database. Moreover, the information of that creature is not a real research in reality, but like the Western dragon, it comes from the fantasy works of the technological world.

The Western Dragons, the Fire Demons, and now the Crypt Lords are all fantasy creatures of the technological world, but now they have become real beings in this world. To be honest, if it weren't for the fact that life in the past few years was extremely real, Ye Zan would probably think that the world he lives in now is some kind of virtual game in the world of technology.

"Crypt Lord, what is that!" Lin Mumu was not far from Ye Zan, and when he heard Ye Zan's muttering, he couldn't help but ask very curiously.

However, before Ye Zan could answer, the crypt lord had already launched an attack on everyone.

I saw the crypt lord, shaking his head and opening his mouth to everyone, and suddenly an extremely disgusting rancid smell swept towards everyone. The people who were sprayed by the rancid breath, although they all had the cultivation of the Yuan Shen Realm, they couldn't bear this stench, and they were actually smoked in mid-air one by one.

Immediately after, the back armor on the back of the crypt lord cracked to both sides, and a black mist rose from the crack in the back armor, and struck everyone with an annoying buzzing sound. The black mist was composed of countless small insects, like a huge swarm of mosquitoes that had been startled in a swamp, like a black whirlwind sweeping in all directions.

Qinghong Zhenjun and the others, after all, are all Yuan Shen powers, although they are dizzy from the rancid breath, they have not lost their combat effectiveness because of this. Seeing the black mist attacking them, everyone immediately used their own means, some sacrificed flying swords to shoot thousands of sword lights, and some cast spells to blast out fireballs, and blasted past in the face of the sweeping black mist.

However, something even more surprising happened, the flying sword of the Yuan Shen power could split the mountains and break the mountains, but it could not kill the insects in the black mist. Those little insects, after being slashed by the sword light, although they crackled and fell to the ground, they soon flapped their wings and flew again, merging into the black mist again. And those fireballs, which should have been the nemesis of the bugs, can only make the bodies of those little bugs brighter at this time, and there is no other use.

"Don't get close to them, let me deal with it!" Ye Zan also found out about the situation, knowing that these little insects had amazing defense, and hurriedly reminded everyone loudly. At the same time, he turned Ruyi into a long sword, and the long sword drew several strange trajectories, pointing a black dot out of thin air in the void. A small black dot, but it has an incomparably powerful attraction, and it is rapidly expanding.

This trick is the black hole devouring, although it is not to create a real black hole, but the powerful attraction is not something that those small flying insects can compete with. I saw that the black mist composed of small flying insects suddenly buzzed a hundredfold, but it was still pulled by the attraction of the black hole, and gradually turned into a black vortex, constantly surging towards the black hole at the center point.

The crypt lord on the ground naturally found out about this situation, and immediately raised his forearm and smashed it towards the ground. And with its seemingly meaningless movements, huge spikes stabbed out from the ground from the void, surrounding Ye Zan. This move looks very much like a move that has been used by Lichao, but those huge spikes seem to be sharper and more difficult to resist.

In the face of such a move, of course Ye Zan did not dare to use his physical body to resist, and the wishful thinking of liquid metal was like a waterfall in an instant. This wishful thinking was ever-changing, and immediately after it appeared, it turned into countless whirling gears, forming a tornado-like barrier around Ye Zan.

Those spikes that stabbed towards Ye Zan instantly pierced into the barrier formed by these countless flying spin gears, and a seeping grinding and sawing sound suddenly sounded in the space. And as the sound sounded, those spikes were quickly consumed, and none of them could penetrate the barrier.

Ye Zan attracted the attention of the Crypt Lord, and the other people around him immediately seized the opportunity and launched an attack on the Crypt Lord below. I have to say that this crypt lord really deserves to have "armor", and the defensive power of that carapace is very amazing, and ordinary attacks can't even leave a trace.

However, Ye Zan's side is all powerful in the primordial gods, and he has seen the defense of that group of small flying insects before, so he naturally spares no effort to attack at this time. The strength of the Crypt Lord is comparable to the power of the Yuan God, and it may even be a few points stronger than the power of the ordinary Yuan God, but after all, it is difficult to defeat the four hands with two fists.

Finally, a loud "boom" was heard, and the body of the crypt lord finally collapsed, but it turned into countless small insects and scattered violently.

Ye Zan had already extinguished the insect mist just now at this time, and when he saw that the crypt lord was actually made up of small insects all over his body, he immediately threw out a gravitational force field with his hand and covered it. The countless insects that were scattered suddenly became extremely slow in the gravitational force field that suddenly increased by a hundredfold, and kept falling towards the ground.

"Twist!" Qinghong Zhenjun let out a low snort, and instantly unfolded the Infinite Sword Realm, enveloping the space where the insect was located. In the Infinite Sword Realm, countless flying swords swirled in the sky and underground, as if it was a huge grinding disc condensed by flying swords. And those insects became the grains on the grinding plate, although they all had amazing defense, they were still instantly crushed and worn out by the "grinding plate".

"Watch around!" Seeing that the Crypt Lord was killed, Ye Zan did not relax in the slightest, but warned everyone again. Through the probe's induction, he had discovered that the ground was constantly experiencing high-energy reactions, and at the same time, the ground of the entire city of vain death had begun to shake violently.

"Boom, boom!"

With a roar, huge beetles broke through the ground, and these beetles were also crypt lords, and their strength was about the same as the previous one. If there is only one Crypt Lord, of course, there will be no difference from the fate of the previous one, and Ye Zan and the others will be able to kill it soon. But now, right around Ye Zan and the others, more than a dozen Crypt Lords have suddenly drilled out from the ground, which is not so easy to deal with.

That Tianyu Dao Ancestor, did he really just want to refine the domain realm and become an immortal?

Seeing those crypt lords on the ground, and thinking back to the existence he had encountered before that did not belong to this realm, Ye Zan couldn't help but have a question in his heart.

Ye Zan was not sure that the Western Dragon must be the "Western Dragon", and the Crypt Lord must be the "Crypt Lord". But he was at least sure that these things must have some kind of connection with the Outer Heaven Demon God in ancient times. So, is the Heavenly Universe Dao Ancestor who uses these things to protect himself really just using these things, or does it have anything to do with the Outer Heaven Demon God?

Can the Refining Domain Realm become an immortal?

Although Xuanyuan Dao Ancestor told Ye Zan that Tianyu Dao Ancestor's purpose was this, he also said that this road was actually impassable. So, Tianyu Dao Ancestor was also the Earth Immortal Dao Ancestor, and he was also the uncle of Xuanyuan Dao Ancestor, could he not know this? If Tianyu Dao Ancestor knew this, if it was true that this road was not passable, then what was the real purpose?
